Abstract
To investigate the effects of Chinese medical herbs on the growth and immunity of Yinxiang chickens,seven Chinese medical herbs such as Astragalus,lanceolata,angelica,medlar,medofenoxate,hawthorn and licorice were added to the diets,and the Newcastle Disease Virus(NDV)vaccine was injected to the Yinxiang chickens on the 3 weeks old.The results showed that the mean body weight and daily gain of the herb group were similar to the antibiotic group,and significantly higher than the control group(P0.05).The spleen and bursa relative weights of the herb group were significantly higher than the control group.The serum antibody titers of anti-NDV of herb group were significantly higher than the control group(P0.05).In conclusion,Chinese medical herbs have significant effect on the growth and immunity of Yinxiang chickens.
